This bug was fixed in the package isc-dhcp - 4.3.3-5ubuntu9 --------------- isc-dhcp (4.3.3-5ubuntu9) xenial; urgency=medium
* debian/isc-dhcp-server.isc-dhcp-server{,6}.service: adjust permissions for most recent PARANOIA commits to avoid granting 'capability dac_override' in the AppArmor profile on second and subsequent starts (LP: #1543794): - /var/lib/dhcp is root:dhcpd and 775 - /var/lib/dhcp/dhcpd{,6}.leases is root:dhcpd and 664 - don't chown /run/dhcp-server to dhcpd:dhcpd since the pid file is now created as root:root and the pid file was not being created before. If this needs to be reintroduced in the future, use root:dhcpd and 775, like with the leases file. -- Jamie Strandboge <ja...@ubuntu.com> Tue, 01 Mar 2016 08:19:43 -0600 ** Changed in: isc-dhcp (Ubuntu) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1543794 Title: isc-dhcp-server fails to start on second & further attempts with 'Can't open /var/lib/dhcp/dhcpd.leases for append' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1543794/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
